IMPROVEMENT IN SASH FASTENING AND HOISTING DEVICE.

Specification forming part of Letters Patent No. 88,049, dated March 23, 1869.

d To all whom 'it may concern.-

Be it known that I, A. W. Lrvines'roNn, of

y Blui'ton, in the county of Wells, and in the vand Hoisting; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the construction and general arrangement of a sash hoister and fastener, the peculiarities of which will be hereafter set forth.

In order to enable others skilled in the art to make and use myinvention, I will now proceed todescribe itsconstruction and operation, referring to the annexed drawings, which form a part of this specification, and in which- Figure lis an inside view of a window-frame with my hoister and fastener attached. Fig. 2 is aview of the left side of the sash, showing the rollers. Figs. 3 an d 5 show the ratchet-bar attached to the right side ofthe sash. Fig. 4 is a plan view of the upper right corner of the sash. Fig. 6 is an outside view of the lock; Fig. 7, a plan view of the same. Fig. 8 shows the key; and Fig. 9 is a section of the right side of the window frame and sashes, showing the T-shaped guide.

A represents a window-frame, and B B the sashes, which are made of any material and dimensions required.

The left side of the sash is provided with two rollers, aa, each, which prevent them from locking, as they are very apt to do when not lifted at the center. The right side of the sash is provided with a strip `of cog-gearing, or ratchet-bar, b, which is attached to sash in any manner suitable. This ratchet-bar runs under and is supported by the T-shaped metallic strip or guide c, which isfastened to the inuerright side of the window-frame A and separates the sash.

The hoisting apparatus consists of a plate, d, which also serves for the lock-plate, and is placed at any suitable height on the frame and sunk into it, so as to form a smooth and even surface.

On the inside of said plate, and in a recess sunk in the window-frame for that purpose, are two ears, which support a shaft, e, and on this shaft is a movable collar, f, which is provided with a cogged pinion, g. Said pinion gears into the cogs on the ratchet-bars?) b, and by that means the sash are hoisted or lowered, as may be desired. The manner of throwing the pinion g in and out of gear with either one of these ratchet-bars will be hereinafter described.

The end of the shaft e extends in a hole on the front part of the plate d, so that its end is even with the surface of the plate, and is turned by means of a key, D, which may be either made fast to and a part of the shaft or separate. I prefer making it separate, as one key may then serve all the windows in a room or in the entire house besides, the appearance is less objectionable than if the key were made part of the shaft and extended beyond the window-frame.

Inside of the plate el, and above the shaft e, is a bolt, h, part of which projects through slots in the plate. These parts extend beyond the face of the plate and enter the space between the cogs on the ratchet-bars b b, thereby securely fastening the sash. To this bolt is attached a lever, fi, by means of a screw passing through a slot on the plate d. This lever has for its fulcrum a screw or rivet, which passes up through the lock-plate.

The circular-head 7c (seen between the lever i and the front of the plate) has a stem, which extends through the plate and connects with a spring below. To this spring is attached a point, which passes through the plate and into a corresponding hole in the lever, thereby arresting the lever in its transit back or forward at the point which securely fastens both sash.'

From the bolt h an arm, m, extends, which surrounds the movable collar f, so that when the bolt is moved by means of the lever t the pinion g is thrown in and out of gear with either one ofthe ratchet-bars b b, as may be' desired.

The mode of operation is as follows: To let down the back sash, place the thumb on the circular h ead 7c and the end of the first finger behind the lower end of the lever i. Now press with the thumb on the circular head until it rests on the plate el now draw the lever gently toward you, at the same time slightly turning the key, if necessary, to bring the space iu the pinion g and ratchetbar b to match. When it is desired to lock the sash, which can be done at any point, it is only necessary to remove the thumb and press the lever gently from you until the head 7c rises, When both sash Will be found to be firmly fastcned. The lower sash is operated by reversing the motions j ust described, and it will be observed that only one sash can be unlocked at the same time.

Instead of only one pinion to operate both sash, I may use two pinions, one for each sash, in which case the sash are secured at any desired point by a spring catch or pawl.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The T-shaped guide c, secured to the Windowcasing A, and the ratchet-bars b b on the sash B B, arranged in combination With the lever z', bolt h, arm m, movable collar f, and pinion g, all substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto setmy hand this 29th day of June, 1868.

A. W. LIVINGSTONE.
